carb questions

[norcal ex]

im thinking about throwing my dual 46s on my ski, but it looks like i need two pulse lines in the case, can i just link those 2 pulses together and run them to the one pulse already on the casE? if not, what do i do?

No, you need 2 fittings in your case. You will have a weak signal to your carb if you only run 1 line. It is an easy job, yamaha left a spot to drill and install a fitting on the other end of the case as the factory pulse fitting.

where can i get the pulse fitting and will it screw up the engine if i drill with the engine together and installed? what happens if i decide to go back to my 38s, do i just cap it off?

what kind of carbs are these?

Blowsion, Riva, pro-tec, pretty much any jet ski shop carries the fitting or a local hardware store might. If you switch back you can cap the extra fitting, mine is capped now since I switched to single carb. The carbs look like modified 44's but I could be wrong.

Some of the cases have the spot to drill and some don't. You can still install the second pulse line in the cases that don't, however there is less meat to drill through. I just used some JB weld to hold it in.
